I am migrating from a ZenCart store to Joomla/JoomShopping.
In my old store, I had a category - photographs, with multiple subcategories - nature, scenic, etc.
EVERY photograph has a set of attributes - SIZE.
ONE of these attributes is - single notecard.
What I would like is that a $3 discount be applied to multiples of 4 single notecards.
Example: 10 single notecards are purchased. 2-$3 discounts are applied.

my demo store in Joomla is here: http://mayonnaise-lovers.com
